Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture in which a socket mounting bracket can be easily attached to the fixture body.

In the conventional lighting equipment, as shown in FIG.
Contact pieces 34 and 34 that come into contact with the bottom plate 33 of No. 2 are provided, and the corresponding contact pieces are spot welded to the instrument body 32 or attached and fixed with screws.

In the drawings, spot welding locations are indicated by X marks.

35 is a reflecting plate.

However, in this conventional device, the socket mounting bracket 31
Since it is attached and fixed to the instrument main body 32 by spot welding or screws, it has the disadvantage of poor workability.

In addition, when spot welding is used, it becomes bulky to transport after welding, increasing transportation costs, and since the socket fitting 31 protrudes from the instrument body, there is a drawback that bruises are likely to occur and the defective rate is high.

The present invention has been devised in view of these points, and one embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the lighting device, in which a straight tube fluorescent lamp 3 is installed between a pair of sockets 2, 2 protruding from through holes at both ends of a reflecting plate 10.

The reflector plate 1 is attached to the socket mounting bracket 5 by screwing each cosmetic screw 4 into the screw hole 7 of the bent tongue piece 6 provided in the socket mounting bracket 5 shown in FIG. 2, and the mounting bracket is attached. The appliance main body 8 is attached to the ceiling surface.

The socket 2 has kerfs 9 on both sides, and the kerfs engage an L-shaped bent piece 10 provided on the top surface of the mounting bracket 5 and abut against a stopper piece 11, thereby allowing the socket 2 to be attached to the mounting bracket 5. Installed.

Therefore, the mounting bracket 5 is U-shaped with bent pieces 12 and 12 on both sides.
The device main body 8 is U-shaped and has upstanding pieces 13 and 13 on both sides so as to fit on the outer surfaces of the new pieces on both sides.

Each bent piece 12 has an L-shaped vertical hooking piece 14 formed by cutting and bending, and an inclined edge 19 that widens upward.
A vertical triangular piece 15 having a vertical edge 23 and a vertical edge 23 is formed by cutting and bending so as to oppose the vertical hooking piece 14.

On the other hand, each upright piece 13 has a vertical hanging piece 1 from its outer edge.
4 is inserted in a horizontal state, and a latching hole 17 that communicates with the slit and vertically rotationally latches the vertical latching piece 14 is bored. An engagement hole 18 is bored into which the vertical triangular piece 15 engages in the upright state.

When installing the mounting bracket 5, as shown in FIG. The vertical locking piece 14 is rotated within the locking hole 17 by raising the vertical locking piece 14 .

Then, the lower part of the vertical triangular piece 15 becomes the upper end surface 13 of the upright piece 13.
′.

When the mounting bracket 5 is further rotated, the inclined edge 19 of the vertical triangular piece 15 slides on the upper end surface 13' of the upright piece 13, and the upright piece 1
3 and the bent piece 12 is pressed against the upper end surface 13' of the upright piece 13, and as the vertical triangular piece 15 passes through the interval, the vertical triangular piece 15 is lowered and engaged. It engages with the matching hole 18.

In this state, both side upright pieces 13.13 and both side bent pieces 12.
12 are restored, and the mounting bracket 5 is fixedly attached to the instrument main body 8 in an upright state as shown in FIG. This contact prevents the vertical triangular piece 151 from being removed from the engagement hole 18 and maintains the upright state of the mounting bracket 5 relative to the instrument body 8.

In this case, the base portion 20 of the vertical locking piece 14 comes into contact with the step portions 21, 21 of the locking piece 17 to restrict the attachment position of the instrument body 8 in the length direction.

Further, although the protrusion 22 of the hooking piece 14 is not necessarily necessary, since the protrusion is located on the outside of the upright piece 13, the upright piece 13.
13 will be prevented from expanding.

In the above embodiment, the vertical latching piece 14 and the vertical triangular piece 15 are replaced by the bent piece 12, and the latching piece 17 and the engaging hole 18 are
is provided in the upright piece 13, but it is sufficient to provide the vertical hooking piece 14 on one of the new bent piece 12 and the upright piece 13, and the latch hole 17 on the other. A vertical triangular piece 15 may be provided on one of the holes 13, and a retaining hole 18 may be provided on the other.

The lighting fixture of the present invention is constructed as described above, and in particular, the bent pieces on both sides of the U-shaped socket mounting bracket and the upright pieces on both sides of the U-shaped fixture body fit into the outer or inner surfaces of the bent pieces on both sides. A latching piece is formed on one side, and a slit through which the latching piece is inserted from the outer edge thereof is formed on the other side, and a latching hole communicating with the slit and rotationally latching the latching piece is formed on the other side. and the both-side bent pieces, and the other side has an inclined edge that presses the one end surface in a direction to widen the distance between the both-side upstanding pieces and the both-side bent pieces. and a vertical triangular piece having a vertical edge that comes into contact with the mouth edge of the retaining hole when the socket mounting bracket is in the upright state on the device body, and that engages with the retaining hole in the upright state. Because of this feature, when installing the mounting bracket, the inclined edges of the vertical triangular pieces can easily widen the distance between the upstanding pieces on both sides and the bent pieces on both sides, and the vertical triangular pieces can be secured to the retaining holes. Once engaged, the vertical edge of the vertical triangular piece comes into contact with the rim of the retaining hole, which prevents the vertical triangular piece from being removed from the engaging hole and prevents the installation. Since the metal fitting is maintained in an upright state on the instrument body, installation workability is improved.

Therefore, there is no need to transport the bulky instrument body after spot welding unlike conventional instruments, and the socket mounting bracket can be easily attached during assembly.

Further, when the locking piece has an L-shaped protrusion projecting to the side of the locking hole, the relative movement of the both side bent pieces and the both side upstanding pieces is prevented, and the vertical triangular piece can be prevented from coming off the retaining hole.
